2.048V fixed output with ±0.05% initial accuracy
That ±0.05% initial tolerance means the output sits between 2.04698V and 2.04902V at 25°C — tight enough for a 16-bit ADC reference without external trimming. A 50°C swing shifts the output by roughly 0.3 mV — the drift stays under one LSB for a 12-bit system measuring a 2.048V full-scale.
That is the band that matters for precision measurement — a weigh scale or strain-gauge front-end sees this noise directly in the DC output. The 10 mA output current can drive multiple ADC reference inputs or a small buffer stage without loading the reference.
